Henry H. Gibson, American Forest Trees
“ Hardwoods—The broadleaf trees are hardwoods. Most, but not all, shed their foliage yearly. It is, therefore, incorrect to classify deciduous trees as hardwoods, since it is not true in all cases, any more than it is true that softwoods are evergreen. Live oaks and American holly are [5] evergreen, and yet are true hardwoods. In a test of hardness they stand near the top of the list.There are more species of hardwoods than of softwoods in this country; but the actual quantity of softwood timber in the forests greatly exceeds the hardwoods. ”
